Congratulations to OE Tuning! The OE Tuning C63 set record times today at the Sacremento Drag strip. With only a tune and full exhaust including headers on pump gas (with drag radials) the car ran 11.15@125 with a 1.763 60 foot. A 60-130 time was run as well which is a new record time for the Stage 2 OE Tuning car at 8.19. Simply fantastic results and 10's are within reach with a better 60 foot. This setup is exactly how the car is driven daily, without the Nitto NT555R drag radials of course.

I don't see how I'm wrong here. Negative DA will produce better results than positive DA.

This run at SAC was in negative DA and just about as good as SAC gets. MIR has seen -2000+. DA is the way we correct slips... it's all based on an established NHRA system.

I know many of the runs done by Mike and others were not in negative DA. I'm not saying they were you seem to be misunderstanding. I am saying MIR is a very fast track that gets some record negative density altitude. Not only it is prepped well, the conditions in the Winter are great. In my opinion, it is one of if not the best track in the country.

you west coast guys seem to see the once in a life time DA drop in MIR and use it for the rest of your lives, the highest DA drop at MIR was in march 2009 -1800DA and after that everytime there was a mercedes event there is never got under -1000DA

i think what you guys see is that we from the east coast race more at MIR and most the ppl beat the records there, if they dont race anywhere else like does 2-3 vette guys and couple other e55 guys how would ppl know if its a great track or not and how can ppl compare to other, i have raced at 4 dift tracks and all 4 are very far from each other and all 4 came within tenths and mph or 2 apart.

the problem is most ppl dont wanna put roll bars in there benz 1 bc its ugly and 2 bc of weight.
no roll bars no under 11.49 or you get the boot, so what we do is we found 2 tracks that let us run how we like when we rent them, im sure if we rent another track that we will let us run how we want you will see the same reuslts within couple tenths and couple mph apart.

what you think Jeramy is not going to do better in Famosa watch him hit 10's there and everyone hates that track.

We sure do, because there is a consistent pattern of insane times coming out of MIR and then the rest of the world seems to think Z06's run 10's stock. MIR is a fast track, period.

It is very important to denote what track, what region, and when times were run. If it wasn't, why would we even bother with calculating DA and don't we need those factors to do it? So again, I do not see how I am wrong here.

I also made sure to point out this run was in negative DA as I went and checked.

Bud, your own record run of 11.199 was in -1500 DA at ATCO. ATCO being another fast track... just like MIR as they both see negative DA.

Also, I just calculated the DA at MIR for a random day in January of this year I picked, the 14th. What was the DA? -3032. Come on...

what you think Jeramy is not going to do better in Famosa watch him hit 10's there and everyone hates that track.

I think he will do better because it is a better prepped track. Why would I think otherwise? I wrote earlier I set my PB at Famoso, not Sac. The prep at Famoso is MUCH better. The conditions aren't as good as SAC though.

I'm not questioning where you guys run or what you do. The cars put up great numbers. I'm pointing out that region and conditions are very valid points to make when discussing a slip.

conditions matter but not that much, we ran mikes car in 40F at MIR -700 -800DA and got a 10.875 at 131 now in 75F we ran his car at 10.789 at 132 and it was positive 1200 DA that 35 degrees dift and over positive 2000DA apart and only hairs apart in time and mph

Yes, but weren't there changes made to his car? I believe catback was added, right?

I believe the impact of conditions is huge. Just seeing the difference the DA calculator makes leads me to that conclusion.

Let's all be honest, we won't see any of these times in the summer. I know, I tried running at Sac in the summer to top my Famoso time in the winter, couldn't do it.

yes he added catback but removed the mcd intake and was running stock air system so that plays its self off,

you rite we wont see best results in summer, but they wont be far away, the thing is with the c63 i dont think heat matters this car LOVES the heat, look at mikes car all his best passes were made after 6-7 hot laps, would you consider that being same conditions as summer if we were in 75F at MIR and running 10 times non stop back to back.

I'm not quite sure of that, but regardless, changes were made so not exactly an apples to apples comparison.

Heat soak is a factor on all motors but to less of an extent on the naturally aspirated M156 vs. the supercharged 55 motors for example.

I don't consider running back to back the same as running in the summer, the air intake is still more dense. I actually set my personal best running back to back as well.

I'm running at Pacific Raceways on 16 April with a few other c63. Temps should be about 40s or 50s, track prep should be good for first test/tune of the year. I have MHP LTs/no cats w/ v3 tune. I hope to have 17" rims/hoosier dr, c/f hood and trunk, and a few other lightweight mods.

That sounds like a nice setup. Who's car supers? What 17's did u guys chose?

ATCO and MIR are definitely FAR BETTER tracks then what we have here on the West.

What tracks have you run at? Don't recall ever seeing a slip.

MIR is usually a very well prepped track, but as Haji has been pointing out we don't get this magical d/a all the time. I ran at 6 events last year and never once in negative d/a. The whole Atco and MIR are the better tracks comments when none of you guys have even run back here is laughable. Records have been made at these tracks...but by guys who have busted their balls to make it happen. It seems there are a lot more diehard racers back here then out west.
